In my vehicle I would like to remove the battery tray to inspect underneath. But I think the bolts holding it down are actually studs attached to the metal plate underneath. These are so corroded they will probably break by removing.

Does anyone know if the metal plate supporting the box can be replaced? It looks like there may be something underneath the plate that is supported by it. I have the manual transmission, which is directly below the battery and support.

The dealer (non-ford) that sold me the vehicle wouldn't remove this to inspect underneath, and Ford Customer service told me there is no technical support that can tell me anything about it, I have to go to the dealer and pay an $80 fee for them to even talk to me.
